My invention relates to'a tool for applying rail anchors to railroadrails I The primary objectof the invention is to provide an improved tool suitable foruse in applying to railroad rails spring yoke rail anchors of the typein which the-yoke ,is.

torsioned and driventransversely of the rail to its applied position.

A more specific object isto provide an im- 10 proved tool of the above character adapted to so engage one jaw end of a rail anchor and the adjacent edge of the rail base that movement ofthe tooltransversely of the rail elevates the lower edge of the saidadjacent jaw to a position abovethe upper longitudinal edge of the rail base flange and also subjects the anchor to the desired torsional stress to move the jaw end of the anchor into a position whereby the gripping surfaces of the adjacent jaw endof the anchor will bear substantially flat against the surfaces of the rail base so as to rovidea firm frictional grip thereon. By t e useof my invention, I minimize the spring pressure of the anchor jaw upon the railbase during the application of the anchor and thereby avoid any substantial swagingor crushingof the sharp forward edge of the anchor jaw as said edge rides upwardly on the inclined top surface of the rail base. j y A further object of the invention is to provide a tool of the above charaeter'which is so constructed as to distribute the pressure of the tool upon the rail base and thereby avoid excessive wearyof the cam surfaces of the tool and which, when the anchor assumes a predetermined position, will be relieved of the spring pressure of the yoke so that the applying tool may be easily removed from the rail. a

The invention consists in the new and improved construction hereinafter described and claimed for ,carryingout the above stated objects andsuch other objects as willappear from the description of the two embodiments of the invention and set forth in the appended claims,

. In order to afford a clear understanding of the operation of my improved device for applying rail anchors to railroad rails, I have illustrated the present invention in connection with a one-piece spring yoke anchor of the type shown in United States Letters Patent No.1,619,902, issued March 8, 1927. The one piece anchor of the type referred to may be briefly described as consistingof a spring yoke '10, formed at one end with a relatively long angularly disposed aw 11 adapted to be hooked over a rail base flange at one side of the rail 12, and formed at the other end with a shorter jaw 13 adapted to illustrates a modified, embodiment be driven into gripping engagement with the haseflange at the. opposite side ofthe rail. The body of the yoke is formed with a normal torsional setso that the jaws 11 and 13, when the anchor is in its initial position on theraihnormally stand at an angle to each other so that it is necessary to twist the an -chor to engage the jaw 13 over the edge of the rail base. a

The anchor herein shown is applied as follows: The angularly disposed jaw 11 is hooked over the rail base, as shown in Fig. 1, and the short jaw 13 is then raised to a position adjacent the'edge' of the railbase. In this position of the anchor, the lower edge 14 of the jaw 13 is slightly below the upper edge of the rail base, as shown in Figs. 1 and 2. The yoke is thentwisted in a direction to .move the yoke from the inclined position shown in Fig. 2 to a position substantially perpendicular to the bottom surface of the rail base (Fig. 4). As soon as the anchor has been twisted sufficiently to permit the edge 14 to clear the upper corner of the rail base, it is driven transversely of the rail from the position shown in Fig. 1, to the position shown in Fig. 5. During this transverse movement of the anchor, the long aw 11 slides downwardly on the inclined top surface of the rail base and the short jaw 13 and the upper edge 15 of the bar 10 are forced into frictional gripping engagement with the top and bottom surfaces, respectively, of the rail base 16.

In the drawings, I have shown two embodiments of my invention adapted for use in applying anchors of the above general type to the base flanges of railroad rails. The embodiment shown in Figs. 1 to 6, inclusive, consists of a member 17 formed with a down-turned flange 18 spaced with relation to the body portion of the member so as to provide a hook shaped portion adapted to embrace the jaw end 13 of the anchor. The vertical edge 19 of the member 17 is formed with a recess 20 adapted to receive one flange of the rail base, and the lower end of the said member is formed with a shoulder 21 adapted to so engage the anchor device as to support it in its initial position on the rail (Figs. 1 and 2). The width of the recess 20 is somewhat greater than the recess below the'jaw 13 of the anchor and also somewhat greater than the portion of the rail base flange received therein and is so disposed with relation to the lower edge 22 of the downturned flange 18 that the said member 17, when in its initial engagement with the rail base (Fig. 1) may assume a position at an oblique angle to the bottom surface of the rail base, as shown in Fig. 2. Preferably the lower edge 23 of the recess 20 and the said lower edge 22 of the flange 18 are tapered in opposite directions to provide cam surfaces 24 and 25 which, when the'member 17 is in its angular position, will bear against the top and bottom corners respectively of the rail base. The said cam surfaces 24 and 25, in addition to being inclined transversely of the rail, are also tapered longitudinally of the rail, so as to provide relatively wide bearing surfaces for engagement with the top and bottom surfaces of the rail base during the various positions assumed by the member 17 (Fig. 6) during the movement of the said member transversely of the rail. The width of the member '17 is preferably such that, when the recessed edge is in engagement with the base flange of the rail, as shown in F ig.-1, the edge 26 of the member will extend beyond the edge 27 of the anchor device, as shown in Fig. 1. In operation, the anchor jaw 11 is hooked over one base'flange of the rail and the jaw 13 raised to the position shown in Fig. 1. The applying tool 17 is slipped over the jaw end 13 of the anchor and moved transversely of the rail until the edges of the cam surfaces 24 and 25 engage the upper and lower corners of the base flange 16 of the rail. The member 17, when in its above initial position supports the jaw end 13 of the anchor. By driving the member 17 transversely of the rail from its initial position, the said cam surfaces are forced over the longitudinal corners of the hae flange and thereby rock the member 17 toward a position perpendicular to the bottom surface of the rail base. The movement of the member 17 from the position shown in Fig. 1 and the position A of Fig. 6, toward the position shown in Fig. 4 or the position C of Fig. 6, subjects the anchor 10 to torsional stress and moves the lower edge 14 of the anchor jaw 13 into a position to clear the upper corner of the rail base. The last named positions of the anchor and applying tool are assumed by said members "when the tool has been driven to such position that the edge :26 of the tool aligns with the edge 27 of the anchor, as shown in Fig. 3. The driving force may now be applied simultaneously to the edges 26 and 27 of the tool and the anchor, so that both IHGITllJCXS will be driven transversely of the rail. The lower edge 14 of thejaw l3 and the upper edge 15 of the body of the anchor move into engagement with the top and bottom surfaces of the rail base before the applying tool reaches the limit of its full movement. This engagement of the anchor with the rail relieves the applying tool from the spring pressure exerted by the twistedcondition of the anchor and consequently removes the frictional engagement of the applying tool on the rail base. lVhen the anchor reaches the position above referred to, that is to say, before it reaches its fully applied position. the applying tool may be readily removed by hand and the anchor then driven home by striking the edge 27 thereof. However, if it is desirable, the applying tool need not he removed until the anchor has been driven home;

In Fig. 7 I have shown another embodiment of my invention, in which a flat bar is provided along one edge with a recess 28 adapted to receive the short jaw end of the anchor. The recess is so formed as to provide a guiding lug 29 for the upper edge of the anchor device and to provide also a seat portion 30 for the lower edge of the anchor. The tool shown in this embodiment is provided with a relatively long handle portion 31 so that the anchor may be twisted with minimum exertion. In this embodiment, the anchor device is twisted and held manually in its twisted position while the jaw end thereof is driven through the guiding recess 28 of the ap 'ilying tool and into operative gripping engagement with the rail base.

While I have described my invention in Flo ' Connection with two specific embodiments,
